This invention relates to improvements in radiator structures and particularly t'o Vthe construction vof the general type of radiator that ormsga part of the cooling system of an internal combustion engine,fsuch as is used on motor vehicles or the like.

The invention isespecially intended for use with and has been embodied in a more or less conventional structure, wherein the heat radiating unit is encased within and suspended :from an ornamental shell that is to be attached to and mounted upon achassis "frame or other suitable support. The usual 'suspension for the heat radiating unit involves the use of a hoop or band to encircle and hold the spaced inlet and outlet-headers and intermediate core,fcom risin the heat radiating unit, in assemble relatlon, which is provided'atintervals with rearwardly and outwardly projecting ears for attachment to the rear edge or radiating unitl is thuslocated forward the point of attachment and instead of heilig directly` mounted upon and rigidlysecured to the chassis frame, its weight is carried by the shell which together with the fact that 'the rearwardly' andV outwardly projecting ears are more or less lieXible, serves to a great extent to free the radiatingunit from racking strains and damaging side thrusts inci-v dent to trameweaving, road shocks and the like. f

In practice it has been found that in some cases, relative movement of a certain nature occurs between the shell and radiating unit, and the inner marginal edge at the front of the shell, which is located adjacent to or in contact with the forward face ofthe core, scrapes or digs into Vthe thin and delicate metal of the core and causes leaks orothcr damage. `Tofavoid this difficulty and still retain the desirable features of the structure referred to, is one of the primary objects of the present invention and to this end it is proposed to provide a simple and economical arrangement for steadying the radiating unit in the shell and reducing the scraping VorrublJing tendency 'of the front face of the core and adjacent edge of the shell.

The radiating unit includes the inlet: and outlet headers or tanks 3 :and 4 respectively and an interposed core 5 preferably ofthe cellular type and comprising a number of preformed lplates pressed from sheet'copper and arranged in spaced pairs to provide a seriesof vertically disposed water passages connecting the top B5 spaces forv the iiow ot' air currents. 4Encircling the core and tank assembly is a hoop for holding the parts in assembled andltor anchoring or suspending thel radiating unit in the shell. This strap may consist, as in the present case, of a top strap 6, a pair of side straps 7, anda bottom strap 8 properly secured together and provided with suitable means to contract the hoop and fdraw it tightly around the radiating unit. c Une" way of contracting the hoop may consist 1n lbending adjacent end portions of the straps 6 and 7 backuponthemselves along inclined lines to form internestingcamy surfaces which when moved laterally with respectto each" 100 o 'extending ears 13 ofthe hoop. f

lin the shell and prevent the marginali edge 18 i of the shell scraping or diggingginto thefront .face of the core 5, itis-proposed to tie or constronger-metal than the thin copper-plates'inthe core-.- The lowermost ends of the strap'7 are turned inwardly beneath the bottom tank and are secured as by welding, soldering or the like to the bottom strap8 whereby the straps 7 and 8 ai'ord in effect a saddle that -icarries the weight of the radiating unit.

. At regular intervals thestraps 6 and 7 are shown provided vwith rearwardly and outwardly-projecting feet or ears 13 for attachment adjacent their rearwardedges as by meansof fasteningbolts 14 with the rearmost --margin `16 of the ornamental casing or shell 15. This rearward portion 16 of the shell is preferably offset inwardly to provide a rest for the engine bonnet orhood while the for- Ywardedgeof the casing wall is t-urned inwardly and rearwardly as at 18 forming `a marginal head, whose inner edge is located adjacent or in contact with the front Vface of To mount the radiator, the shell 15 maybe provided with a mountingstrap anchorband 20 secured atits ends as by rivets 21 to the side wall ofthe shell and as by hold-down bolts 22 to the frame'member 2. Thus the radiator shell vissupported upon the chassis frame and thefradiating unit inV turn is suspended in the-shell through'the rearwardly 1 In order tosteady the heat radiating unit nect the hoop encircling the core land tanks to the shell or supporting member in a manner to restrain the tendency of the edge/.portion 18 and core to move toward each other.

' f For this purpose the opposite ends of the bottom strap 8 may be extended beyond the ,point of connection yof the side straps 7 to form earsr25 which may be provided with openended'slots26 for registry with the bolt openings 1n the strap or bar 20 so that the ears may be secured beneath the heads of the ybolts 22. This bottom strap 8 and its extensionsy or ears 25 are preferably ofy light A'gage sheet meta1,.so formed as tobe slightly flexiblein a direction at right angles to the plane. of the strapwhile it will be relatively rigidor non-flexible in the direction of its plane.V Thus the-,ears 25 will not transmit strains to the' radiating unit nor'hold the unit rigid relative'to the chassis frame member `but'it will resist the tendencyfor to and fro movement of theV face of the core and th@ the marginal edge 18 relative to each other.

In Figs. 5 and 6 the invention is shown applied to a radiator in which the structural details are slightly different from those heretofore described. In this case the bottom and side portions of the anchorage hoop are formed integral or in one piece and the loeating ears instead of being extensions of the bottom strap consist of separate plates welded or otherwise securedl to the bottom portion' 31 of the hoop and provided with notches 32 through which extend the fastening bolts 33 for securing to the support or frame 34the anchor strap 35 which supports the shell 36.

Another type of Vhoop is shown in Fig. 7 wherein'40 is a bottom strap whose opposite end portions are turned upwardly and secured as by soldering or welding to the side straps 41, the lower portion of the side strapsH being turned inwardly for engagement with the side wall of the bottom tank as at 42. As in the arrangement shown in Fig. 5, slotted plates 43 are provided for attachment to the underside of the strap and for detachable engagement beneath the heads of the fastening bolts 44 which secure the anchoring strap or bar 45 of the shell 46 to the frame member 47.

It `will be apparent that by the use of sep arate ears 43, the invention may be applied to those radiators already in use, or may be embodied by the manufacturer in his present product without requiring material changes in methods of manufacture or the necessity for making up new dies or revising the existing machine set-up.

Various modifications of the invention may be readily made as will be apparent to those skilled in the art.

I'claim: Y

1. In a radiator structure for motor vehicles, a shell, a supporting strap therefor attachable to the vehicle frame, a radiating unit, and a hoop encircling said unit including a pair of side straps having rearwardly and outwardly projecting ears for attachment to the rearward edge of the shell to suspend the unit in the shell and a bottom strap having ears extending therefrom and engaging the attachments between the strap and frame, for steadying the suspension of the unit in said shell.

2. In a radiator structure, a core unit, a shell through which the radiator structure is mounted on a support, said shell having its rear edge portion connected with the core unit to directly suspend the core unit therein and its front edge portion adjacent to but unconnected with the face of the core, and means to prevent movement of said front edge portion and the face of core to and from each other, including a plate-like element ilexible in directions other-than in the plane thereof, interposed between the bottom of' the core unit and the shell with its plane placed in the direction of the to and fro movement to be resisted. v 3. In a radiator structure for motorvehicles, a shell through which the radiator structure is mounted on the vehicle, a core unit enclosed within and carried by' the shell, and a flexible but inextensible tie connection between the bottom of the core and the shell to steady the core and hold it against move'- ment in a direction transverse to the face of the core while permitting movement in other directions.

In testimony whereof I aix mysignature. JAMES A. WHITE.
